Heritage

This paper examines the role of digital technologies in advancing archeological research, using two complex, stratified case studies—the Villa Reale of Haghia Triada in Crete and the rock-cut churches of Pantalica in Sicily—as reference points. Both sites, despite their geographical and chronological differences, present comparable challenges: fragmented evidence, incomplete documentation, and the need for multi-scalar interpretation. By integrating photogrammetry, LiDAR scanning, and other 3D acquisition techniques with 3D modeling approaches, this paper explores how digital workflows can both preserve and reinterpret fragile archeological contexts. The aim of this research is to critically assess the methodological potential and epistemological implications of these tools, emphasizing transparency, reproducibility, and their communicative value for scholarly communities and wider audiences.

Paper-based heritage objects are commonly stored in archival boxes, books, and paper stacks, creating confined microclimates that may differ from the surrounding environment. While room-level climate control is central to preventive conservation, object-level conditions are shaped by enclosure permeability, hygroscopic buffering, ventilation, and internal emissions. This study investigates temperature, relative humidity, air exchange, and gaseous pollutants inside archival boxes, bound books, and paper stacks under laboratory and real storage conditions. Air exchange rates were determined using CO₂ tracer decay, while climates were monitored over periods from hours to one year. Chemical conditions were assessed using passive sampling of air pollutants, oxygen measurements, and dosimetric methods. The results show that boxes, books, and paper stacks behave as semi-permeable rather than sealed systems. Hygroscopic buffering attenuated short-term RH fluctuations, especially within books and paper stacks, while long-term internal conditions followed ambient trends with pronounced time lags. Restricted ventilation limited the ingress of external pollutants but could allow for internally generated gases to accumulate. Experiments using acid-sensitive indicator paper demonstrated the slow penetration of acetic acid into paper stacks. Overall, enclosure performance reflected a balance between buffering capacity, permeability, and chemical reactivity rather than airtightness alone, highlighting the importance of object-level microclimate assessment in preventive conservation.

Communicating heritage to contemporary audiences, especially younger generations, is a central challenge in Heritage Education. This study aims to analyse audience perceptions of the documentary Amato Lusitano: Ciência e Humanismo—a cultural mediation tool designed and produced by the authors—and to verify the association of these perceptions with sociodemographic profiles. Framed within an action research methodology, the study combines artistic creation and empirical analysis of public reception. During the first screening, a questionnaire was administered to 55 viewers (37 students aged < 40), and data were submitted to an exploratory factor analysis. This revealed a two-factor structure, highlighting a primary factor—Communicative and Educational Effectiveness—with high internal consistency (α = 0.89). Participants reported high agreement with this dimension, with statistically significant differences across generational groups (p < 0.005). Participants with less prior knowledge about Amato Lusitano showed a greater perception of novelty. Clarity of information and quality of the content were the most valued aspects. In contrast, duration and accessibility emerged as areas for improvement. The potential of the documentary as a heritage education resource for initial teacher training is evident. It is necessary to develop more modular, dynamic content ecosystems tailored for young audiences.
